Since the classical molecular dynamics simulator LAMMPS was released as an open source
code in 2004, it has become a widely-used tool for particle-based modeling of materials at …

Shock loading takes materials from ambient conditions to extreme conditions of temperature
and nonhydrostatic stress on picosecond timescales. In molecular materials the fast loading …

Ultrafast radiographic imaging and tracking (U-RadIT) use state-of-the-art ionizing particle
and light sources to experimentally study sub-nanosecond transients or dynamic processes …

Physics-informed neural network architectures have emerged as a powerful tool for
develo** flexible PDE solvers that easily assimilate data. When applied to problems in …

The sensitivity of heterogeneous energetic (HE) materials (propellants, explosives, and
pyrotechnics) is critically dependent on their microstructure. Initiation of chemical reactions …

Fully dense structures of high solids loaded polymer composites printed via material
extrusion additive manufacturing are of interest across many applications, including …

Shock initiation and detonation of high explosives is considered to be controlled through hot
spots, which are local regions of elevated temperature that accelerate chemical reactions …

Regions of energy localization referred to as hotspots are known to govern shock initiation
and the run-to-detonation in energetic materials. Mounting computational evidence points to …

The response of high-energy-density materials to thermal or mechanical insults involves
coupled thermal, mechanical, and chemical processes with disparate temporal and spatial …

All‐atom molecular dynamics (MD) and Eulerian continuum simulations, performed using
the LAMMPS and SCIMITAR3D codes, respectively, were used to study thermo‐mechanical …
